Abstract: A mains power supply unit for the purpose of supplying consumers that are connected directly or by way of a voltage system converter to a direct voltage branch of a mains power supply unit comprises a buffer capacitor (C) that can be charged from the mains supply and that still supplies the direct voltage branch for a predetermined minimum period of time in the event of a failure or interruption in the mains supply. In such an event, the buffer capacitor (C) can be charged by way of a dedicated charging circuit (3) to a voltage (U2), which, regardless of the voltage fluctuations in the direct voltage branch, is substantially constant and corresponds in a substantial manner to the upper limit value of the direct voltage (U1) to which limit value the mains power supply unit is dimensioned. The buffer capacitor can be connected onto the direct voltage branch by way of a controlled switch (S) in the event of undervoltage in the mains supply or in the direct voltage branch.
Patent AT-A208092-A (AT)
IPC: B28D1/08
Filed: 1992-10-21
Abstract: The invention relates to a device on wire sawing machines for sawing natural and artificial stone and the like with saw wires (2). The saw wire rotating device sets the saw wire (2) in a continuous forced rotary movement about the longitudinal axis of the wire. The rotary movement results from the saw wire (2) rolling laterally between the different diameters of the wire inlet region and the wire outlet region of the profile of the wire rotating roller (1). A guide roller (3) (3') is provided for setting the lateral offset (q) between the wire inlet and the wire outlet. In one exemplary embodiment of the invention, the drive roller (1') of the wire sawing machine can at the same time be the wire rotating roller of the saw wire rotating device according to the invention. The wire rotation produced by the saw wire rotating device effects a uniform and concentric wear pattern of the saw wire (2) until the end of its service life. <IMAGE>

Abstract: ABSTRACT OF THE DISCLOSURE   A process and apparatus are provided for the removal, by absorption and oxidation, of objectionably odoriferous inorganic sulphur compounds from gaseous mixtures thereof.  The process includes the first step of prescrubbing the gaseous mixture by: passing the gaseous mixture upwardly in intimate gas/ liquid contact in a contact zone with downwardly flowing alkaline liquid scrubbing medium; recirculating partially spent liquid scrubbing medium; and sparging a pool of the partially spent liquid scrubbing medium with air; and the second step of scrubbing the prescrubbed gaseous mixture by: passing the prescrubbed gaseous mixture upwardly in intimate gas/liquid contact in a con-tact zone with downwardly flowing liquid scrubbing medium comprising an aqueous, neutral-to-alkaline solution of sodium, potassium or calcium hypo-chlorite having a concentration of available chlorine of between 10mg/1 to 60,000 mg/l; and recirculating partially spent liquid scrubbing medium com-prising  hypochlorite solution.  The apparatus includes a first or upper coun-tercurrent  gas/liquid scrubbing section and second or lower countercurrent gas/liquid scrubbing section, each section including external recirculation legs provided with make-up liquid inlet lines.  The process and apparatus thus uses the convenient technique of wet scrubbing that produces low enough residual concentration of sulphur compounds essentially to eliminate the odor problems.

Abstract: STACKED FLEXIBLE DISK STRUCTURES          Abstract Semi-rigid washers are coaxially disposed to form an air-permeable spindle for coaxially supporting flexible record disks.  A plurality of such washers and disks is coaxially stacked to construct a flexible disk file. Washers preferably have an annular shoulder with a depth slightly different than the thickness of the record disks for firmly supporting and aligning same in the coaxial stack.  Alternatively, disks may be adhesively secured to a radial outward portion of each washer.  Additionally, each washer has a plurality of radially extending air passageways for facilitating radial air movement which controls the stack of flexible record disks.  A radial inward portion of each washer abuts each adjacent washer for forming a firm axial stack of disks.  A rigid stabilizing plate at each axial end completes the assembly. The present invention is an improvement over that shown by Penfold et al in commonly assigned, copending Canadian application Serial Number 211,526 filed October 16, 1974, and entitled "Multiple Flexible Disk File".

Abstract: ABSTRACT OF THE DISCLOSURE        A biologically weighted ultraviolet radiant energy monitor provides a direct indication of the hazards to humans from the energy emanating from an optical radiation source.          The radiation is first spectrally dispersed by passage through a suitable prism or diffraction grating.  Portions of the dispersed radiation are mechanically masked in accordance with a predetermined biological weighting.  The weighted output from the mechanical mask is then fed to a suitable detector.          In the various embodiments of the ultraviolet hazard monitor, a quartz prism or diffraction grating spectrograph is utilized to spectrally disperse the incident radiation spatially and a plate coated with sodium salicylate or other suitable converter is placed in the exit plane of the spectrograph.  The sodium salicylate plate fluoresces in the blue in response to incident ultraviolet radiation.  The intensity of the biologically weighted blue light may then be conveniently and readily detected by a blue sensitive detector to provide an immediate readout of the potential ultraviolet radiation hazard from the unknown optical source.

Abstract: Abstract of the Disclosure A DC electrical motor of the form having one field winding connected in series with the armature winding in addition to a shunt field winding connected in parallel with the armature winding is provided with a diode or the like in the shunt field winding circuit. This blocks reversed current flow in the shunt field winding which can otherwise occur during start-up due to an inductive interaction with the series field winding and armature circuit. The diode or the like enables faster magnetization of the stator poles by preventing creation of negative shunt field ampere turns due to the magnetic couple with the series field-armature circuit during the motor start period. Faster starting of the motor results, and adverse effects such as heating, brush deteriora-tion, and commutation problems are reduced.

Abstract: Abstract of Disclosure Disclosed herein is an engine having opposed cylinders with a guided rotary and reciprocating piston which telescopes over an output shaft and transmits rotary motion directly to the output shaft without the need for a crankshaft.  Guided rotary movement of the piston is afforded by rollers rotatably supported on a radial pin on the cylindrical wall of the piston.          The rollers travel in an elliptical type groove on the inside surface of the cylinder to impart rotary motion to the piston as a result of rectilinear motion of the piston caused by com-bustion of fuel in the working chambers on opposite sides of the piston.  The engine can also be operated by an external source of pressurized gas or operated as a pump.  The rotary motion is transmitted to-the output shaft by a rider block which has a square cross section and which is fixed to the output shaft and is complementary in shape to a square opening in the piston.          The rider block is movable between end walls in the piston.          Circular openings with cylindrical seals seal the output shaft to the piston.
